Rv with best gas mileage

There are many options when it comes to which rv has the best mileage. It will all just come down to how you drive and the many different factors that decide how much miles you get per gallon.

Which Factors Affect RV Gas Mileage?

There are a few different factors that affects rv gas mileage.

• Speed

It does not matter which type of gas vehicle you drive, the speed at which you travel will determine how many miles you get per gallon. Other factors of speed will have to be taken into consideration also. Factors such as how fast you got up to the optimal speed or how slow you got up to that optimal speed. The optimal speed for the best gas mileage is at around 55-65 MPG. Any more than that speed, gas mileage will decrease.

• Wind

Wind speed has an effect on gas mileage in the fact that travelling head-on into high winds will cut your gas mileage down. It might not be by much, but it will definitely be lower than it should be. Vice Versa, if you have the wind blowing in the direction you're travelling.

• Ethanol Content

Ethanol Content plays a major roll in the amount of miles you get per gallon.

• Weight

The lighter your rv is the better the gas mileage will be. The lighter the rv you purchase, the more gear you will be able to tow or carry without affecting your gas mileage by too much.

• Grade

Just like many different factors on this list, grade has a lot to do with getting the best gas mileage out of your rv. Any vehicle

• Fuel Type

I know this is a blog post about gas mileage, but i have to put it in here that diesel vehicles get better miles per gallon than a gas vehicle. Diesel engines provide 10-15% more energy than its gas counterpart as well as providing more low-end torque. If a gas vehicle uses 1 gallon of fuel for every 20 miles traveled, its diesel counter-part will go 20-30% more miles on the same amount of fuel.

How to get the best fuel mileage in your rv

• Change your air filters frequently

Something that seems so simple as changing your air filter on a schedule plays a big role in the mileage you get out of your rv. Rule of thumb when changing your engine oil and oil filter is to check to see if your air filter has gotten less efficient in any way. This could be by inspecting to see if there are any foreign objects restricting airflow through it. Other factors that will affect the effectiveness of your filter are how often you drive within the city or on the highway, or the type of climate you live in. The type of fuel you use will also be a factor in how often you have to change or check your filter.

Diesel vehicles are usually fitted with an “Air Restriction Indicator”. This indicator alerts the driver whenever it is time to replace the filter.

• Check Tire Pressure

There is a tire pressure recommendation on the wall of all tires. This recommended tire pressure is there for us to use as a guideline to get the best performance out of our tires as much as possible.

• Pack Light

The heavier the weight of any vehicle, the worse the gas mileage will be. Therefore, anything you add to your rv also adds to the weight which in turn makes your rv have worse gas mileage.

• Do regular maintenance

Since it will assist your Recreational Vehicle to run at the ideal level, it is essential to keep up with all the basic upkeep of your motorhome. By keeping up with all the basic upkeep, your engine will run much better. All other parts need to be changed at their required interval to have everything working perfectly.

Maintenance items to regularly check

• Brake replacement
• Tire Pressure
• Engine Checkup
• Tire replacement/rotation
• Check all fluids
• Etc

Keeping everything up to date and doing all necessary maintenance will surely give better gas mileage as all parts will be working in their best state.

The Class C motorhome weighs a little bit more than a Class B motorhome does. This is because of the additional trailer area, from the overhanging part of the trailer, and since Class C motorhomes are normally larger than Class B motorhomes. Like with Class B and Class A, this wind flow and weight distribution is why the Class C motorhome is ranked second amongst other rvs and their mileage capabilities.

The average mileage that a Class C Motorhome gets is around 14 to 18 miles per gallon.

What makes a fuel efficient motorhome great?

A fuel efficient motorhome can be considered any motorhome that delivers gas mileage that is comparable to regular vehicles. Even if you get a couple miles less per gallon depending on the size of the motorhome you have, you can still consider ypur motorhome to be fuel efficient if it doesn't break your bank every time you go to fill up.

Most fuel efficient rv

The most fuel efficient rv listed in this blog post is the Winnebago Travato 59G. The Roadtrek Sprinter RS Adventurous is also listed as getting exceptional gas mileage. These two rvs get as good gas mileage as some regular cars on the road today. I currently drive a 2013 Hyundai tucson and only get 20 mpg on a good day.

Diesel Upfront Cost

Diesel rvs are on average way more expensive than gas powered rvs. This is the reason why most new rv owner opt-in for gas powered rvs. However, there are many benefits to having a diesel rv. Here we will explain why diesel rvs cost more and how they can be advantageous for you to buy.

You should consider owning a diesel rv as it will save you money in the long run because it does not fluctuate as much as gas prices do.

Gas Mileage Help

Here are some items to help with your rv's gas mileage.

• Octane Boost - Cleans injectors To Improve Engine Performance



This octane booster will help with the performance of your engine but most importantly, it will give you better gas mileage by cleaning your injectors. I usually only use one of these when i go on longer trips.

This is why doing the necessary research into the different types of rvs that are available is a must. I have learned that rushing into buying my first vehicle was a big mistake, do not be like me.
